But there’s more to user generated content than blogs and there’s more to searching user generated content than looking for material that is relevant or opinionated or highly rated by readers or authors. In this talk, a number of user generated

Antonella Zucchella,Sabine UrbanP) suggests that, for optimal retrieval, documents should be ranked in order of decreasing probability of relevance. In this paper, we present a new document ranking paradigm, arguing that a better, more general solution is to optimize top-. ranked documents as a whole, rather than ranking them inde

We show that: (1) topic models are effective for document smoothing; (2) more rigorous topic models such as Latent Dirichlet Allocation provide gains over clu

To date most SCIR systems have focussed on providing various awareness tools in order to enable collaborating users to coordinate the search task. However, requiring users to both search and coordinate the group activity may prove too demanding. On the other hand without e

This generalization is achieved by introducing secondary features correlated with term weights and applying regression to predict term weights given features. To improve support for more focused retrieval like question answering, we c
